Nicer <Folder> structure for combined VisualD project files.

[visuald generator] When generating a combined VisualD project file, generates nicer <Folder>. ...

Each source file structurePath is now relative to its own package.
                    Note: all sub-packages are conflated to the same <Folder>, because it seems VisualD can't display folder names with a colon.

Update change log.

Implement -debug=xyz flag.

Fix handling of packages with no configurations. See also #99.

Avoid redundant dependencies and .lib dependencies in generated VisualD projects if possible. ...

Any redundant dependency can cause "multiple definition" linker errors.

Remove outdated sentence and add a link to the package format description.

Reducing log spam

The dependency in terms of the DependencyGraph is the base package and not the sub package. ...

Only enqueue one update action for the same package.

Added some very basic unittests for the DependencyGraph

Little doc improvement.

Add -shared flag for DMD when building dynamic libraries.

Little doc improvement.

Implement a new graph based algorithm for configuration resolution. ...

The old algorithm failed to chose a valid configuration for many complex dependency graphs (worked reliably only for trees).

Fix handling of global build settings for packages without configurations.

Generalize common compiler switches in the form of a BuildOptions enum. ...

Related changes:
 - translation of DMD compiler switches to other compilers is generalized
 - application of build requirements is generalized
 - added support for debug versions
 - supporting almost all compiler settings for generated VisualD projects now

Avoid specifying compiler flags that are already handled by special fields in the VisualD generator. See rejectedsoftware/vibe.d#269.
